【摘要】：為解決高海拔地區(qū)低壓和低氧環(huán)境帶來的隧道施工供氧、通風(fēng)等技術(shù)難題,采用現(xiàn)場試驗(yàn)及測試的方法,對高海拔隧道施工人員缺氧狀況、供氧效果、機(jī)械排污量等進(jìn)行研究,結(jié)合理論推導(dǎo)及數(shù)值計(jì)算,得到如下結(jié)果:人體的缺氧危險(xiǎn)等級分為嚴(yán)重缺氧(Ⅰ)、缺氧(Ⅱ)、存在缺氧危險(xiǎn)(Ⅲ)和不缺氧(Ⅳ)4級;基于肺泡氧分壓與氧氣體積分?jǐn)?shù)關(guān)系的不同缺氧等級下的氧氣體積分?jǐn)?shù)控制標(biāo)準(zhǔn);不同海拔CO體積分?jǐn)?shù)控制標(biāo)準(zhǔn)模型;基于風(fēng)管開口處流量理論的風(fēng)管漏風(fēng)率海拔修正系數(shù)計(jì)算公式;風(fēng)機(jī)風(fēng)壓、功率的海拔修正系數(shù)公式;考慮人體勞動(dòng)的平均能量代謝率海拔修正系數(shù)的不同海拔下施工人員勞動(dòng)強(qiáng)度指數(shù)及強(qiáng)度等級。
[Abstract]:In order to solve the technical problems in tunnel construction such as oxygen supply and ventilation caused by low pressure and low oxygen environment in high altitude area, the hypoxia condition, oxygen supply effect and mechanical sewage discharge of tunnel workers at high altitude were studied by field test and test method.In combination with theoretical derivation and numerical calculation, the following results were obtained: the human body was classified into four levels of severe hypoxia (鈪，
